FIRE Puzzle

Other Puzzles

This puzzle consists of two identical components that screw together.
It is made of nylon by selective laser sintering. The name comes from
Plato's association of the tetrahedron with the classical element of fire.

I made 100 of these as my IPP28 exchange puzzle.

Separately, the pieces look like this.  It is tricky to put them together.

The solution is that you start assembling the two pieces like this, then screw them together.

Here is the description page that was printed in the IPP28 book.
